UNITED STATES PATENT 6 Claims.

This invention relates to devices for treatment of the hair,.and more particularly to hair curlers.

- One of the objects of the invention is to provide a curler on which the hair my be wound and clamped with means for latching or looking the hair and curler together. Heretofore, curlers have consisted of a tubular body or mandrel on which the hair is wound, a clamp which may fit over the hair, and a locking means for looking the parts together, but this locking means has proven more or less unsatisfactory. Existing curlers of the type mentioned have proven unsatisfactory because in use the roller or latchmg means has a round peripheral surface which does not grip or sufficiently engage the end of the mandrel to prevent slippage of the roller and clamp. These objections have been overcome and an eflicient clamping means provided by employing a roller or disk of polygonal form which cooperates with the tubular. end of the mandrel. Such a polygonal or, to be more specific, octagonal roller readily snaps over the end of the mandrel and seats itself in position. Such an octagonal roller is further advantageous; since the various fiat surfaces and angles facilitate engagement by the fingers when moving the roller to and from clamping position.

In the drawing: 30 Figure 1 is a plan view of one form of curler utilizing my improvement; I

Figure 2 is a side elevatiomof the curler shown in Figure lfpartly broken away to disclose details; 35 Figure 3 is a side elevation of another form of curler utilizing the invention, and

Figure 4 is a perspective view of the improved polygonal roller.

Referring to the drawing, the improved roll- 4 er or one part of my improved latching means is shown at It and is made from any suitable elastic or resilient material. such as rubber. This roller is polygonal and preferably octagonal as shown, thereby providing a multiplicity of 45 surfaces ll about the periphery- An axial opening I2 is provided through the roller.

The roller ill may be employed in the form of curler disclosed in Figures 1 and 2, which type of curler is disclosed merely by way of ex- 50 ample, since the roller may be used in other forms of curlers of the present general character.

This curler has a metallic tube or mandrel l4 to which a metallic law I! is pivoted by meansof inturned ends of a resilient wire or wire- 5 like clamp or ball 11. The' metallic -wire clamp has a. straight intermediate portion passing through the opening l2 of the roller and thereby pivotally mounting the 'roller on the ball. The sides of the bail are sloped toward the narrow portion i8 as clearly shown in the drawing. 5

1 The roller is of greater diameter than the bore of the tube or mandreLso that only a portion of the roller may enter the adjacent opened end of said tube to effect better coaction of the surfaces H with the .wall of the tube It. Said 10 mandrel II and jaw l5 are preferably perforated, as at l9 and 20' respectively, to facilitate the passage of air through the device and hair.

In the use of my improved curler, while the jaw I5 is raised, the hair is wrapped about the 15 fectively clamping such bail or clamp securely and in an accurately centered position. The ridges formed by the intersection of the flat sides ofthe roller iii tend to create sufiicient leverage to permit the roller toclip or slip in the roller I0 is seated in the tube or mandrel, ll. When in locked position, one'whole side of the roller I0 is seated in the tube or mandrel, the roller compressing slightly in riding over the edge of the tube. I

Practically the same operation takes place.

when using the form of curler disclosed in Figure 3, andthe roller lllespecially functions in a similar way. In this form, the tube or mandrel of thecurler is shown at W preferably being'tapered and havinga finger grip II at its free end. The jaw is shown at I5 pivoted to the tube or 40 mandrel M by a ball or clamp I1 substantialLv identical with 'that shown at H. Said jaw I5 has a finger grip 22 at its end opposite to the grip 2|, such grips 2| and 22 being operable to move the jaw and mandrel relatively. 5

Various changes may be resorted to, provided theyfall within the spirit and scope of the invention. I

What I claim is: 1 1. A roller for coacting with an end of a hair 5 curler to secure clamp means thereof in hairclamping position, the roller being polygonal.

- 2. A roller for coacting withv an end of a hair curler to secure clamp means thereof in hairclamping'posltion, theroller being octagonal.

bail carried by said means, and a resilient roller mounted pivotally on the bail to clip into engagement with an end of the tubular means, said roller having a polygonal periphery.

6. In a curler, a mandrel, a clamp pivotally secured to one end of the mandrel, a clamping bail also pivotally secured to one end of the mandrel, and a clamping roller mounted on the bail for engagement with the other end of the mandrel, said clamping roller being octagonal in shape, with one whole side seated in the open end of the mandrel.
